Which means files are split into roughly equal-sized parts and stored in a different countries. By encrypting files MEGA can work with a larger number of data hosting companies around the world, decreasing the likelihood of a Megaupload-style seizure of servers by one government. Therefore, they cannot be responsible for the contents of uploaded files. Since Mega does not know the encryption keys to uploaded files, they cannot decrypt and view the content.

Data on Mega services is end-to-end encrypted client-side using the AES algorithm.
